Canon SX40 HS vs Sigma DP2

In this article, we are evaluating the Canon SX40 HS versus Sigma DP2, one being a Small Sensor Superzoom and the other is a Large Sensor Compact by manufacturers Canon and Sigma. There is a big difference among the sensor resolutions of the SX40 HS (12MP) and DP2 (5MP) and the SX40 HS (1/2.3") and DP2 (APS-C) feature totally different sensor dimensions.

The SX40 HS was announced 2 years later than the DP2 and that is a fairly big gap as far as camera tech is concerned. Both of the cameras offer different body type with the Canon SX40 HS being a SLR-like (bridge) camera and the Sigma DP2 being a Large Sensor Compact camera.

Before going through a in depth comparison, below is a concise view of how the SX40 HS grades versus the DP2 in relation to portability, imaging, features and an overall rating.

Following is a sample of the gallery pictures for Canon PowerShot SX40 HS and Sigma DP2. The whole galleries are available at Canon SX40 HS Gallery and Sigma DP2 Gallery.

For anybody who is aiming to carry your camera, you will have to think about its weight and proportions. The Canon SX40 HS has outside dimensions of 123mm x 92mm x 108mm (4.8" x 3.6" x 4.3") with a weight of 600 grams (1.32 lbs) and the Sigma DP2 has measurements of 113mm x 60mm x 56mm (4.4" x 2.4" x 2.2") with a weight of 280 grams (0.62 lbs).

Don't forget, the weight of an Interchangeable Lens Camera will vary depending on the lens you have attached during that time. The following is the front view over all size comparison of the SX40 HS vs the DP2.

Factoring in size and weight, the portability score of the SX40 HS and DP2 is 64 and 86 respectively.

Often, its difficult to envision the contrast in sensor sizing simply by seeing a spec sheet. The graphic below will help offer you a much better sense of the sensor dimensions in the SX40 HS and DP2.

As you can see, each of the cameras enjoy different megapixel count and different sensor sizing. The SX40 HS using its smaller sensor will make shooting shallower DOF harder and the Canon SX40 HS will provide greater detail with its extra 7MP. Greater resolution will also allow you to crop photos far more aggressively. The more recent SX40 HS is going to have a benefit in sensor technology.
